(2) Deaf animals, undergoing sham surgery. (3) Deaf animals undergoing surgery and injection of solvent (artificial perilymph). (4) Deaf animals undergoing surgery and injection of artificial perilymph containing BMSCs.
Results: DP-Gram in rat with normal SB525334 hearing undergoing sham surgery show that procedure has neither negative impact on normal cochlear nor on deaf cochleas. No significant difference (p = 0.25) between ears excludes artificial perilymph as
a confounding factor. There is no significant difference between ears in animals receiving BMSCs.
Conclusions: Implanted cells with normal histologic structures have no physiologic function and hearing rehabilitation. Further studies by monitoring the survival of these cells with histologic and appropriate biomarkers will help to investigate differentiation process of these cells. (C) 2012 Elsevier Ireland Ltd.

“Cupressus arizonica
Greene is an aromatic evergreen coniferous plant with great importance in urban horticulture and in the pharmaceutical and fragrance industries. The hydrodistilled volatile fruit oil of cultivated C. arizonica from northwest Iran was analysed find more by GC/MS. Forty-three components were identified, accounting for 96.4% of the total oil. Monoterpenoids (91.9%) dominated the identified components of the essential oil, followed by a lesser portion of sesquiterpenoids (4.2%). Monoterpene hydrocarbons (87.9%) were the principal subclass of components, with -pinene (54.3%), -myrcene (11.1%), -3-carene (6.5%) and Mizoribine limonene (6%) as main constituents. -Pinene (4%), terpinolene (2.8%) and camphene (1.1%) were the other monoterpenoids present in notable amounts. -Terpineol (1.4%) was the only representative of the oxygen-containing monoterpenoids.
Sesquiterpenoids had a minor share in the volatile oil’s composition. Hydrocarbonic compounds (91.1%) had a higher share compared to the oxygenated components (5%). Comparison of the essential oil profile of C. arizonica Greene plants cultivated in Iran showed remarkable quantitative but slight qualitative differences with previous reports from other parts of the world. In summary, the chemical and percentage composition of the studied oil from cultivated C. arizonica Greene from northwest Iran was characterised by a high occurrence of -pinene and -myrcene, and is thus competent for use in related industries and as a favourite ornamental aromatic tree.”
“Objective: The purpose of this study is to assess complications occurring after cochlear implantation (Cl) in children and to discuss revision surgeries and medical interventions occurring during follow-up. Study design: Retrospective study of 475 consecutive pediatric cochlear implantations at a tertiary referral center.
Methods: The patients(n = 475) who received cochlear implants in our institution between March 2000 and March 2012 were followed up (range, 5 months-12 years).
